I can only fix things about which I get feedback so it incrementally
gets better.  I'm sorry you found it difficult.

"test-text" should contain one or more examples of broken text that
needs to be fixed.  "make check" will spin a file with that text in it
and run the "fixinc" program, then run a recursive "diff" between the
patched files and a set of example files.  Any differences are highlighted.
So, when you make a fix, you should pretty well understand how the
broken text ought to be transformed.  In the "make check", you ought
to see a diff that includes that new transform in the new output and
not in the sample output.

That means first, ensure the header you want fixed is fixed.
Then, incorporate the brokenness in the "text-text" field.
Then, ensure it is fixed in the sample output.
Then, add the fixed result into the baseline sample files.

That means send me email if you are still having problems.
